The former Melrose Place star, 44, was released from the Edna Mahan Correctional Facility for Women on parole last June after serving two and a half years of a three-year prison sentence for a fatal drunk driving incident in 2010. On Friday, the Superior Court of New Jersey filed an appeal, requesting a re-sentencing, as prosecutors believe the original downgraded sentence was too lenient.

According to court documents obtained by ET, the state's issue on appeal is that Locane-Bovenizer's sentence is "illegal because the judge did not impose the correct period of parole ineligibility" and the sentencing court "abused its discretion in imposing a downgraded sentence."

The Somerset County Prosecutor's Office says the sentence sent a "bewildering message" about the penalty for driving under the influence, NJ.com reports. Locane-Bovenizer, who was convicted of vehicular homicide and assault by auto, could have been sentenced for 15 years.

Locane-Bovenizer was convicted of the lesser-degree offense of second-degree vehicular homicide. The trial judge believed longer jail time would be detrimental to her two children, one of whom suffers a serious medical and mental disability, the Associated Press reported at the time.

The accident occurred June 27, 2010, following a cast party Locane-Bovenizer had attended. She then drove to a barbecue and left around 8:30 p.m. On her way home, she drove her SUV into the passenger side of a silver Mercury Milan (she was traveling 53 mph in a 35 mph zone). Helene Seeman was a passenger in the Milan vehicle, which her husband, Fred Seeman, was driving. The 60-year-old woman was pronounced dead at the scene from severe blunt force trauma. Her husband was left critically injured.

A trial judge found Locane-Bovenizer guilty of driving while intoxicated in a school zone, leaving the scene of the accident and reckless driving. Court documents revealed she was under the influence of alcohol and Ativan.
